## Using Device Info Plus

Import `package:device_info_plus/device_info.dart`, instantiate `DeviceInfoPlugin`
and use the Android and iOS, Web getters to get platform-specific device
information.

Example:

```dart
import 'package:device_info_plus/device_info_plus.dart';

DeviceInfoPlugin deviceInfo = DeviceInfoPlugin();
AndroidDeviceInfo androidInfo = await deviceInfo.androidInfo;
print('Running on ${androidInfo.model}');  // e.g. "Moto G (4)"

IosDeviceInfo iosInfo = await deviceInfo.iosInfo;
print('Running on ${iosInfo.utsname.machine}');  // e.g. "iPod7,1"

WebBrowserInfo webBrowserInfo = await deviceInfo.webBrowserInfo;
print('Running on ${webBrowserInfo.userAgent}');  // e.g. "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:61.0) Gecko/20100101 Firefox/61.0"
```

:::caution
To get serial number on Android your app needs to meet one of official [requirements](https://developer.android.com/reference/android/os/Build#getSerial())
In case the app doesn't meet any of requirements plugin will return `unknown`.
